SIDE FR TRUCKS.

Specification of Letters Patent.

Patented May 9, 319ML To all whom t may conce/rn Be it known that LBASILMacon, a subject of the King of Great Britain, anda resident of theborough of Manhattan, in the city of New York, vcounty and State of NewYork, have invented an lmprovement in Side Frames for Trucks, of whichthe :Following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

The object of the invention is to providean improved construction forthe ,side trames of car trucks with a view toward simplicity in themanufacture and assembling of said frames and also toward getting themaximum strength out of a given,

amount of metal.

rlhe drawings wherein the improvements are illustrated contain,

Figure l, a view in elevation of a frame embodying the invention. Fig.2, a top plan View, and, Fig, 3, a view in section, the plane ot whichis indicated by the line 3*;3 in Fig. l. Y

The top arch bar a, the bottom arch Z) and the tie bar c are all relatedin the usual manner and are preferably formed of channel iron, the upperbar with its channel facing upwardly, that of the bottom bar facingdownwardly and the tie bar lying along or being embraced by the channelof the bot tom bar. To resist the shear acting along the ends where thebottom bar and top bar are fastened together, ridges al are pressed inthe bottoms oi' the channels a and b so that when 'these bars are placedtogether,

the ridges in the channel b will iit into those in channel a. y Such aconstruction is very simple and takes most ofthe shearing strain(indicated by the arrows) which would otherwise come upon the Yfasteningboltsor rivetsn The truck `columns e' are formed as side members of ayoke f which is preferably a wrought steel member and channeled. Thechannel faces outwardly so that' it may be made to embrace the top andbottom arch n,

bars between which it is located. Thus, as shown, the bar c lies withinthe channel of the yoke at the top and is riveted thereto; and the endsof the side-members e are bent inwardly so that the channels of theseshort sections overlie the bottom arch bar Zw. Upon these shortsections, the end of the spring plank g rests, the bottom arch bar b andthe tie bar c being pressed upwardly between the short bent-in `sectionsof the.l l

yoke, so as to meet the spring plank g to which they are riveted,` thespring plank also beingv .riveted to the side members or truck columnse. .Such a construction prou vides a very strong support for the springplank as the metal is not weakened by bolt v holes and the like wherethe shear comes, as in the case of many of the presentv constructions.

lt will be obvious that the present. conl claim as my invention:

l. A sideframe for a vcar truck having a top bar, a bottom bar, and achanneled yoke the side members of which are bent inwardly atthe bottomand constitute the` V truck columns, the top bar lying within thechannel connecting .the .said side members and the bottom bar extendingthrough the channels on each of the bent-in portions of the said sidemembers. f

2. A side iframe for a car truck having a top bar, a bottom bar, a tiebar, and a channeled yoke the side members of which are bent inwardly atthe bottoms Aand constitute the truck columns, the top bar lying withinthe channel connecting the said side members, the bottom bar extendingthrough the channels in' each yof the bent-in portions of said sidemembers, and the tie bar lying within the channel of the bottom bar.

3. In a car truck, vthe combination with a spring plank, of a side framehaving a top bar, a bottomfbar, and a yoke having side members bentinwardly at the bottoms and constituting the truck columns, the end ofthe spring plank resting upon the bent-in portions of the yoke. i

4. ln a car truck, the combination with the spring plank, of a sideframe having a top bar, a bottom bar, a channeled yoke between the topand bottoni bars with the vchannel facing outside and the bars being 5.ln a car truck, the combination with the spring plank, of a side :tramehaving a top channeledbar with the channel facing upwardly, a bottomchanneled bar with the channel facing downwardly, a" channeled yokebetween said bars with the channel y facing outside and the bars beingembraced thereby, the ends of the side members of the yoke being` bentinwardly upon the bottonr bar and the end of the spr-ing plank resting7. A side frame for car trucks comprising Lipper and lower channel barsand an interposed U-shaped member, y' the contiguous ends of saidchannel'bars being provided with cooperatingv corr-ugations extendingtransversely across said bars.
